  • Publication number: 20210356169
    Abstract: A heat exchanger for a water heater having a burner includes an outer tube extending longitudinally along a centerline from a first end adjacent the burner to a second end. Indentations are formed along the length of the outer tube and extend towards the centerline. An inner member extends through the outer tube and between the indentations such that flue gases from the burner flow in a passage between the inner member and the outer tube from the first end to the second end of the outer tube.

  • Publication number: 20210356171
    Abstract: A flue collector box for a furnace having a cooling coil, a heat exchanger, and an inducer blower includes a housing having an interior chamber in fluid communication with the heat exchanger such that condensation generated in the heat exchanger flows to the interior chamber of the housing. A valve is connected to the housing and includes a pair of lips defining a fluid passage through the valve in fluid communication with the interior chamber. The lips have an open condition allowing condensation to exit the valve when the inducer blower is deactivated. The lips have a closed condition forcefully engaging one another when the inducer blower is activated to prevent condensation from exiting the valve.

  • Publication number: 20210254860
    Abstract: A burner for use with an igniter for firing a flame into a heat-exchanger includes a body having a sidewall that defines an interior chamber. A first opening in the body receives a pre-mixed mixture of air and fuel. A second opening in the body is in fluid communication with the first opening. A distributor is connected to the body and closes the second opening. The distributor includes a first portion and at least one curved second portion provided on the first portion. Each second portion includes a plurality of first perforations in fluid communication with the first opening in the body. The first perforations of one second portion are positioned adjacent to the igniter such that ignition of the pre-mix mixture flowing through the first perforations results in a flame through the second portion. A flange extends around the first portion and includes second perforations.

  • Patent number: 10955134
    Abstract: A fuel burner includes a tube extending from a first end to a second end and including a central passage and fluid directing structure for directing a mixture of air and combustible fuel radially through the tube. The fluid directing structure collectively defines a total flow area. A blocking member is axially movable within the central passage between a first condition blocking a first percentage of the total flow area and a second condition blocking a second percentage of the total flow area different from the first percentage to control the flow of the mixture of air and combustible fuel through the fluid directing structure from the first end to the second end of the tube to be ignited.

  • Publication number: 20210080119
    Abstract: A fluid directing structure for a direct fired appliance having a heating space, a burner for providing heat to the heating space, and an exhaust includes a duct. The duct includes a first passage extending from a first end adjacent the burner to a second end fluidly connected to the exhaust. A second passage extends from a first end fluidly connected to the first passage to a second end fluidly connected to the heating space. A damper is connected to the duct and has a first condition directing fluid flow from the first end of the first passage to the second end of the first passage while preventing fluid flow to the second passage. The damper has a second condition directing fluid flow from the first end of the first passage to the second passage while preventing fluid flow to the second end of the first passage.

  • Publication number: 20150342737
    Abstract: Apparatuses and method of using them, for restoring and reshaping the mitral valve annulus and reduce or restore the lengthwise geometry of the heart. These apparatuses may include two or more support chords each having an anchor at the distal end for connecting to a valve annulus, and an elongate length. The support chords may be held within a thin delivery cannula. Also include a bendable/conformable apical cradles to which the proximal end of the chords may be attached. The attachment to the cradle or sling member may be adjustable, so that the length of the chords may be adjusted from outside of the heart later. Attaching the support chords to the valve annuls and anchoring on either side of the apex region of the heart may reshape both the mitral valve and the ventricle length.

  • Publication number: 20150342717
    Abstract: A temporary valve and a filtration device can be added to a delivery catheter or guide catheter to improve hemodynamics and provide embolic protection. Both the valve and filter can mount onto the outer diameter of a delivery or guide catheter, which offers several distinct advantages. First, the inner lumen of the delivery or guide catheter remains unaffected, thereby allowing the standard procedure steps to take place without any changes or interruptions, or with minimal changes or interruptions.

  • Patent number: 9161660
    Abstract: A deep fryer apparatus including a gas burner for heating cooking oil. The burner includes a venturi inlet for receiving fuel and combustion air that communicates with a main chamber having an expanding cross-section. A balancing plate is disposed in a flow path of the fuel air mixture that is located intermediate the inlet and the outlet. The balancing plate defines a region of reduced cross-section in the flow path. A flame cap located at the outlet defines at least one secondary chamber between itself and the balancing plate that defines a flow path cross-section that is larger than the cross-section of the flow path at the balancing plate. The balancing plate is preferably tapered to compensate for variations in the length of the flow path due to an angled orientation between the burner inlet and the outlet.

  • Patent number: 9068761
    Abstract: A gas burner including a burner body having a lower housing, an inlet conduit and a combustion surface element attached to the lower housing. A diffuser/reflector positioned within the body encourages even distribution and mixing of a combustible gas/air mixture. The diffuser/reflector is preferably of a sheet metal construction and includes a plurality of stamped openings with each of these openings having an overhanging guide plate. The combustion surface element includes a plurality of integrally formed rigidizing ribs and is made from a high temperature steel alloy wire cloth. The inlet conduit is secured directly or indirectly to an access door/bulkhead that is used to close off an access opening formed in a water heater wall through which the burner is installed. In one construction, an air scoop shrouds the inlet conduit and at least partially defines a flow path of primary air, substantially isolated from the combustion chamber.

  • Patent number: 9062879
    Abstract: A burner nozzle for use in burning a gas/air mixture includes a tubular member that extends along a centerline and has a mixture supply passage extending from an inlet end that receives air and gas to an outlet end. The outlet end includes a plurality of exit portions in fluid communication with the inlet end. The exit portions are positioned on opposing sides of cooperating dimples formed in the tubular member. The dimples are configured to shape the exit portions into nozzles having a cross-sectional area that decreases in a direction towards the outlet end.

  • Publication number: 20140228843
    Abstract: A system and method for resecting a valve in a patient, in which the system includes: a proximal frame and a distal frame opposite the proximal frame, each frame including a plurality of interconnectable frame segments, in which the proximal and distal frames are separated by an adjustable distance and positionable on opposite sides of the valve; an electrode, adjacent to the valve on at least one of the proximal and distal frames, that electrosurgically resects valve tissue; a proximal chamber and a distal chamber coupled to the proximal and distal frames, respectively, that allow passage of fluid and captures at least a portion of resected valve tissue, in which each chamber selectively operates in one of a radially collapsed mode and a radially expanded mode; and a drive system that adjusts the distance between the proximal and distal frames.
